There are many many variables in radiator design. Dimensions, crossflow 
vs vertical tube, core thickness, number of tubes, tube size, staggered 
vs in-line tubes, fin design, fin count...
It's a lot more than just aluminum vs copper/brass.
Air flow is just as important as the core (heat exchanger).

On the under the FAQ section is an explanation as 
why aluminum radiators cool better than copper ones.  Granted, these 
sell aluminum radiators, but the answer seems to make some sense. FWIW.
